摘要

摘要: 气体钻井过程中因地层出水引起的井壁失稳等技术难题,严重制约了该技术的推广应用。为解决这一难题,将合成的超吸水材料用于携带地层出水,并根据计算模型预测的出水量确定超吸水材料加量,携水工艺模拟装置可以确定超吸水材料适用的出水范围。实验结果表明,计算模型能对地层出水进行准确预测;合成的超吸水材料饱和吸水倍数为825 倍、在5 min 内吸水达到656 倍、在矿化度为1 000 mg/L 的水中最小吸水倍数为120 倍、在pH 值为6～11区间内的吸水倍数都大于600 倍,在较高温度和压力下,保水率仍大于80%,能够满足大庆地层出水条件下气体钻井的携水要求。对吸水材料回收后,其饱和吸水倍数为700 倍,可以重复利用;模拟装置能对不同出水量的携水工艺进行有效模拟,解决了以往模拟装置体积大、操作难等问题。研究结果表明,将超吸水材料应用于出水地层的气体钻井,为保持井眼干燥、扩大气体钻井应用范围提供了新的解决方向和技术思路。

Abstract: Air base drilling fluids are suitable for drilling pressure depleted formations and wells with serious mud losses, but water cut restricts the use of this technology. To solve this problem, a synthesized water absorbent is used to carry water out of hole, and the amount of the water absorbent is calculated based on a computational model. A testing device simulating the water carrying process was developed for predicting the amount of the water absorbent suitable for a certain range of the volume of water cut. Laboratory study shows that the computational model can be used to accurately predict the amount of water cut. The reusable water absorbent has the properties of fast absorption, high absorption capacities, and resistance to salt, acid and alkali. Temperature and pressure have small effect on the performance of the water absorbent. This new device is capable of simulating water cut of different volumes, and compared with previous devices, this device is smaller and is easy to operate.
