哈里伯頓業(yè)務(wù)部門Sperry Drilling宣布，推出JetPulse高速遙測(cè)服務(wù)，該服務(wù)可提供鉆井和地層評(píng)估測(cè)量的連貫高數(shù)據(jù)速率傳輸。這個(gè)新遙測(cè)系統(tǒng)可以幫助作業(yè)者做出更快的決策，優(yōu)化井位，改善井控，同時(shí)提高鉆井效率。

JetPulse服務(wù)能夠在廣泛的深度范圍和復(fù)雜的井眼軌跡中連續(xù)傳輸井下數(shù)據(jù)，物理數(shù)據(jù)速率高達(dá)每秒18位。它可為任何高速遙測(cè)系統(tǒng)提供高井漏(LCM)偏差，幫助操作員泵出所需的LCM濃度，從而在不改變或堵塞井底組件的情況下避免泥漿損失。該系統(tǒng)還可縮短鉆井曲線的平穩(wěn)時(shí)間，通過結(jié)合新的遙測(cè)技術(shù)與隨鉆測(cè)量/隨鉆測(cè)井(M / LWD)服務(wù)，大限度地提高滲透率并優(yōu)化儲(chǔ)層接觸。這樣操作人員可以做出更早和更有效的決定，以便在單次運(yùn)行中鉆探時(shí)間更長(zhǎng)。

“在需要大量數(shù)據(jù)集合的環(huán)境中，如深水區(qū)和成熟油田，運(yùn)營(yíng)商依靠井下數(shù)據(jù)的準(zhǔn)確性和時(shí)效性來作出關(guān)于油井的明智決策，并預(yù)計(jì)單道部分。” Sperry Drilling部門副總裁 Lomar Duhon表示。“JetPulse是高速遙測(cè)系統(tǒng)的下一個(gè)發(fā)展版本，能夠?qū)崿F(xiàn)準(zhǔn)確的井位和減少鉆井時(shí)間，以大限度地提高客戶的資產(chǎn)價(jià)值。”

該服務(wù)還包括JetPack 3D井下數(shù)據(jù)管理功能，可將多個(gè)數(shù)據(jù)集合壓縮并安裝在一個(gè)程序包中，實(shí)現(xiàn)超過每秒140位的有效數(shù)據(jù)速率，使操作人員可以在鉆取時(shí)獲得正確的數(shù)據(jù)，從而加強(qiáng)決策。

近有亞洲地區(qū)的運(yùn)營(yíng)商部署了JetPulse，主要原因是其目標(biāo)儲(chǔ)層部分以上的地層壓力較高，生產(chǎn)區(qū)高度超標(biāo)。操作人員需要頻繁更新隨鉆壓力(PWD)數(shù)據(jù)，以快速調(diào)整鉆井參數(shù)和等效泥漿重量或等效循環(huán)密度，以避免不必要的壓裂和/或差異卡住。

JetPulse提供所需的壓力數(shù)據(jù)，幫助操作員預(yù)測(cè)潛在的挑戰(zhàn)，并在任何非生產(chǎn)性時(shí)間之前對(duì)動(dòng)態(tài)鉆井環(huán)境做出反應(yīng)。操作人員在預(yù)算范圍內(nèi)到達(dá)生產(chǎn)區(qū)，不會(huì)破壞油井或允許不需要的地層流體進(jìn)入。此外，JetPulse為該地區(qū)的運(yùn)營(yíng)商提供了快的泥漿脈沖傳輸速率。

Halliburton launches new high-speed telemetry service

HOUSTON -- Sperry Drilling, a Halliburton business, has announced the release of JetPulse high-speed telemetry service, which provides consistent, high-data rate transmission of drilling and formation evaluation measurements. This new telemetry system helps operators make faster decisions to optimize well placement and improve well control while increasing drilling efficiency.

The JetPulse service transmits downhole data consistently over wide depth ranges and complex well trajectories with physical data rates up to 18 bits-per-second. It provides the highest lost circulation material (LCM) tolerance of any high-speed telemetry system, helping the operator pump the required LCM concentration to cure mud losses without changing or plugging the bottom hole assembly. The system also reduces flat time on the drilling curve, maximizes rate of penetration and optimizes reservoir contact by combining new telemetry technology with measurement/logging-while-drilling (M/LWD) services. This allows operators to make earlier and effective decisions to drill long sections in a single run.

"In environments requiring large data sets such as deep water and mature fields, operators rely on the accuracy and speed of downhole data to make informed decisions about their wells and expect single-run sections," said Lamar Duhon, V.P. of Sperry Drilling. "JetPulse is the next evolution of high-speed telemetry systems that enable accurate well placement and reduced well time to maximize customers' asset value."

The service also includes JetPack 3D downhole data management, which compresses and configures multiple data sets in one package, giving effective data rates of more than 140 bits-per-second so operators can get the right data while drilling for enhanced decision-making.

An operator in Asia recently deployed JetPulse where there was high formation pressure in the zone above the targeted reservoir section and a high overbalance in the production zone. The operator needed frequent updates of pressure-while-drilling (PWD) data to quickly adjust drilling parameters and equivalent mud weight or equivalent circulating density to avoid unwanted fracturing and/or getting differentially stuck.

JetPulse provided the pressure data needed, helping the operator anticipate potential challenges and react to the dynamic drilling environment before any non-productive time could occur. The operator reached the production zone within budget and without fracturing the well or allowing the entry of unwanted formation fluid. In addition, JetPulse delivered the fastest mud pulse transmission rates for this operator in this region.
