哈里伯顿推出深水完井多层隔离方法

油田服务公司哈里伯顿发布了可用于超深水条件下完井作业的XSTMZ系统。

新的XSTMZ系统可用于深水和最大压力为15000psi的超深水条件下完成油井作业。

XSTMZ系统中的额定压力，是根据该公司增强型单程多区（ESTMZTM）方法中额定压力为10000psi的基础上设计的。

新系统下能使施工者以更高的泵注速率和更大的支撑剂体积来隔离和压裂填充多个地层。

XSTMZ系统还能支持构造隔层，以便更好地利用高低压差对特定的长期产油层进行增产。

哈里伯顿公司在一份声明中说，“增强XSTMZ系统的能力有助于降低多余压力来提高压差，从而提高产量和最终采收率，并可通过单次下钻作业时隔离和处理多个井段来节省钻井时间。

新系统将由墨西哥湾低第三系（Gulf of Mexico Lower Tertiary）的一家主要运营商使用，用于部分油藏因枯竭而导致井底压力差异较大的油藏。

随着新系统的部署，将改善墨西哥湾下第三系长产层的增产和砾石充填效果。

该公司计划明年开始安装设备，以便完成两口油井。

哈里伯顿完井业务副总裁马克·道森说:“采用了15000psi的XSTMZ系统，我们可以在更富挑战性的地层中获得最大产量，同时与传统完井方法相比，还可以进一步缩短完井时间。”

“我们ESTMZ系统的成功已经帮助运营商在全球完成了200多个独立区块，我们很高兴看到我们的工程完井解决方案继续满足客户在超深水区域的需求。”

【Psi】 Pounds per square inch，是一种计量单位。美国习惯使用psi作单位，意为磅力/平方英寸。1psi=6.895kPa=0.0689476bar =0.006895MPa

Halliburton launches multizone system for deepwater operations

Oilfield services company Halliburton has unveiled the Xtreme Single-Trip Multizone (XSTMZ) system for extreme deepwater conditions.

The new XSTMZ system can be used for completing wells in deepwater and ultra-deepwater conditions up to 15,000 per square inch (psi).

The pressure rating of the XSTMZ system is designed align="justify">It enables operators to isolate and frac pack multiple zones at higher pump rates with larger proppant volumes.

The XSTMZ system also supports the creation of zonal compartments for better stimulation of long pay zones with high-pressure differentials.

Halliburton said in a statement: “The increased capability of the XSTMZ system helps increase production and total recovery by driving down abandonment pressure and can save rig time by isolating and treating several intervals with a single trip.”

The new system will be used by a major operator in the Gulf of Mexico Lower Tertiary to complete multiple reservoirs that experience large bottomhole pressure differentials due to the exhaustion of some of the reservoirs.

With the deployment of the new system, stimulation and gravel packing of long pay zones will be improved in Gulf of Mexico Lower Tertiary.

The operator intends to start equipment installation next year for the completion of two wells.

Halliburton Completion Tools business line vice-president Mark Dawson said: “The introduction of the 15,000psi rated XSTMZ system allows us to maximise production in even more challenging formations while further reducing the time required to complete these wells versus conventional systems.

“The success of our ESTMZ system has helped operators complete over 200 independent zones globally, and we are pleased to see our engineered completion solutions continue to meet our customers’ needs in ultra-deep water.”
