因此，低渗透油藏开发初期使用菱形反九点井网，菱形主对角线平行裂缝方向，沿裂缝注水增加边井受效程度，拉大的井距又可抑制注水井排的角井过早水淹，且利于整体压裂改造；中后期将菱形反九点井网的角井转注形成交错排状注水方式，从而保持较高的采油速度和阶段采出程度。

In order to tackle the difficulties including the sidetracking, the reentrance of the main hole, the well bore trajectory control, and the poor drillability of the formation, some technologies are put forward, such as the sidetracking technology of compound holes, the pipe string reentrance technology of main holes, the well bore trajectory control technology, and the drilling speed increasing technology. All the technologies have been applied to the field successfully, greatly shortening the drilling cycle and guaranteeing the safe and fast completion of the well.

油藏工程理论及现场实践均表明，注水开发低渗油藏其注水方式和注采井数比对注水波及体积及水驱采收率有较大影响，通过对注水井水驱控制面积、单井控制面积与注采井数比进行了试探性回归分析，再结合谢尔卡乔夫公式，推导出了水驱采收率、驱油效率、井网指数、注采井数比与井网密度的关系式，从而建立了水驱油藏宏观井网密度公式。

To avoid lost circulation or wellbore instability when drilling fluid circulated downhole after gas drilling, or to shorten drilling cycle and reduce drilling costs, it is recognized that the cementing quality needs to be improved further. 18 dryhole cementing jobs have been tried in 339.7 mm and 244.5 mm holes in Sichuan and Chongqing oil or gas fields and a set of technology for dryhole cementing after gas drilling is developed, including wellbore preparation, casing running, incontinuous liquid slurry injection, etc.

为了避免气体钻井结束后替入钻井液可能引发的井漏、井眼不稳定等复杂情况，缩短钻井周期、降低钻井成本，进一步提高固井质量，在川渝地区探索实践了气体介质条件下339.7 mm表层套管和244.5 mm技术套管共18井次的干井筒固井作业，基本形成了一套气体钻井后干井筒（井眼内为纯气体时的井筒简称为干井筒）固井工艺技术方案与措施。

萨北油田位于大庆长垣萨尔图油田纯油区内，随着油田的开发，特别是二、三次加密调整井及过渡带扩边井，油水界面不同于基础井网；应用井壁取心分析资料总结了萨北油田水淹层与原始油水同层的评价方法；统计萨北油田30口井，其中4口过渡带井，其余为二、三次加密调整井，应用井壁取心分析资料区分该区油水界面位置附近不同水洗程度、原始油水同层及原始水层，应用效果较好。

The results show that the water breakthrough time shortens with the increase of the horizontal well length. Under the same well space and production conditions, the water breakthrough time of five-spot pattern is longer than that of seven-spot and nine-spot pattern. With the increase of angle between the horizontal well and the horizontal direction, the water breakthrough time shortens in five-spot well pattern, firstly increases and then decreases in seven-spot pattern, and increases in nine-spot pattern. The influence of reservoir and fluid parameters on the water breakthough time is little.

计算结果表明，井网的见水时间随水平井长度的增加而缩短；相同的井距和生产条件下，五点法井网的见水时间要长于九点法和七点法井网；随水平井与水平方向夹角的增大，五点法井网的见水时间缩短，七点法井网的见水时间先增加后缩短，九点法井网的见水时间增加；油藏和流体参数对井网见水时间影响不大。
