Description

Technical Field

[0001] The invention relates to the technical field of oil and gas exploration, and in particular to a method, a device, a medium and equipment for calculating the water yield of a drilling formation. Background Art

[0002] In oil and gas drilling, gas drilling is a drilling method that uses compressed gas as a circulating medium, and gas drilling can significantly improve drilling efficiency. Among them, nitrogen drilling is a gas drilling method that uses nitrogen as a circulating medium. Since nitrogen is a non-flammable and non-combustible gas, its chemical properties are very stable. Therefore, in gas drilling, nitrogen drilling has the advantages of greatly increasing drilling speed, avoiding reservoir pollution, and reducing drilling costs. It is a drilling technology that is widely used at home and abroad.

[0003] Because nitrogen drilling usually presents a large negative pressure difference in the wellbore, when drilling into an aquifer, the formation fluid enters the wellbore under the negative pressure difference, resulting in formation water. Formation water may cause annular obstruction or even form a mud cake ring. In addition, the dry water-sensitive rock mass around the wellbore wall will hydrate and expand under the action of formation water, causing the wellbore to shrink, causing drill sticking, and even causing complex situations such as wellbore wall instability.

[0004] The current methods for calculating the water yield of nitrogen drilling formations mainly include geological and hydrological data analysis, well logging data analysis, perforation water layer testing and drilling monitoring. All of the above methods have the problem that the calculated results deviate greatly from the actual water yield.

[0005] Combined with the current gas drilling water detection technology, a reasonable and accurate method for calculating the formation water output is needed. Summary of the invention

[0195] Drilling data of the wells X12 and X27 that have been drilled in a certain work area are collected, including parameters such as well depth, inlet pressure, outlet temperature, outlet humidity, formation water production rate, and gas injection rate. The inlet pressure, outlet temperature, and outlet humidity are plotted according to the well depth as shown in the following figure. Figure 5 and Figure 6 A curve diagram of Figure 5 This is the curve chart of Well X12. Figure 6 This is the curve chart of Well X27.

[0196] Based on the collected data and combined with the curve chart, the well section before water production is divided. The well section with a depth of 1185m to 1198m in Well X12 and the well section with a depth of 1317m to 1335m in Well X27 are the well sections before water production.

[0197] Calculate the average inlet pressure and outlet temperature of the well section before water comes out of the formation.

[0198] According to the collected data and combined with the curve chart, the well section after formation water production is divided. Starting from the depth of 1199m, the inlet pressure, outlet temperature, outlet humidity and other parameters of Well X12 began to increase, indicating that the formation began to produce water, and the parameters continued to increase, indicating that the formation water production was increasing, reaching the maximum value at the depth of 1235m, and then remained relatively stable, indicating that the formation water production remained basically constant. Starting from the depth of 1335m, the inlet pressure, outlet temperature, outlet humidity and other parameters of Well X27 began to increase, indicating that the formation began to produce water, and the parameters continued to increase, indicating that the formation water production was increasing, reaching the maximum value at the depth of 1388m, and then remained relatively stable, indicating that the formation water production remained basically constant.

According to the formation water production collected from wells X12 and X27, the formation water production in this section of well X12 is 2.2m 3 / h; the formation water yield in this section of Well X27 is 2.0m 3 / h, the calculated formation water production rate of well X12 is 611.1 g / s, and that of well X27 is 555.6 g / s.

[0200] The data of the well section after water production from the formation of Well X12 and Well X27 were combined and multiple regression analysis was performed to obtain the regression coefficients C1, C2, C3 and C4. C1 = 12.3792, C2 = 332.2704, C3 = 71.6627, C4 = 0.

[0201] The formula for calculating the water yield of the drilling formation is as follows:

[0210] By performing multiple regression analysis on the parameters of the wells drilled in a certain work area and the formation water yield, a calculation model for calculating the formation water yield of nitrogen drilling was obtained. This method is easy to operate, has high accuracy, and is easy to implement on site. Using the logging data of nitrogen drilling in a certain work area, the parameters with a strong correlation with the formation water yield were selected: inlet pressure, outlet temperature, and outlet humidity. They are common with existing gas drilling sensors, compatible with the current detection system, and have strong adaptability.
