據(jù)世界石油2021年7月27日?qǐng)?bào)道，哈里伯頓公司日前推出了ExpressFiber，這是一種一次性使用光纖電纜，可以提供精確、直接的地下測(cè)量，包括井間通信，在價(jià)格上能夠使每個(gè)井場(chǎng)的壓裂作業(yè)監(jiān)控成為可能。

　　了解和優(yōu)化井和壓裂干擾是目前作業(yè)者面臨的重大挑戰(zhàn)。 ExpressFiber使用分布式聲波傳感(DAS)獲得微地震、應(yīng)變和溫度的直接測(cè)量，這與其他井間監(jiān)測(cè)技術(shù)提供的間接估計(jì)不同。

　　與我們的智能壓裂和地下監(jiān)控服務(wù)配對(duì)的ExpressFiber提供實(shí)時(shí)的裂縫增加和井間干擾情況，幫助作業(yè)者改進(jìn)完井設(shè)計(jì)，提高總體資本效率。

　　ExpressFiber是常規(guī)井間監(jiān)測(cè)中最經(jīng)濟(jì)的光纖解決方案。 它對(duì)作業(yè)幾乎沒有影響，可以在幾小時(shí)內(nèi)泵入探邊井內(nèi)。 這種一次性光纖可以在壓裂作業(yè)前或壓裂作業(yè)期間安裝。

　　ExpressFiber能夠在增產(chǎn)處理過程中經(jīng)受住井下條件的考驗(yàn)，并且不會(huì)對(duì)探邊井井眼的后續(xù)壓裂作業(yè)造成影響。

　　Halliburton launches low cost, direct fracture monitoring service

　　Halliburton Company introduced ExpressFiber, a single-use fiber optic cable that offers accurate, direct subsurface measurements, including cross-well communication, at a price point that enables fracture monitoring on every well pad.

　　Understanding and optimizing well and fracture interference is a significant challenge that operators face today. ExpressFiber uses distributed acoustic sensing (DAS) to acquire a direct measurement of micro seismic, strain, and temperature unlike other cross-well monitoring techniques that provide indirect estimates.

　　ExpressFiber, paired with our intelligent fracturing and subsurface monitoring services, provides real-time actionable insights of fracture growth and well interference, allowing operators to improve completions designs and gain overall capital efficiency.

　　ExpressFiber is the most economic fiber solution for routine cross-well monitoring. It has little to no impact to operations and can be pumped downhole in offset wells within a couple of hours. This single-use fiber can be installed any time before or during the fracturing operation. ExpressFiber is designed to withstand downhole conditions for the duration of the stimulation treatment before degrading and has no impact to subsequent fracturing operations in offset wellbores.
