Description
Technical Field
The invention relates to the technical field of oil and gas exploration and drilling, in particular to an automatic drilling fluid filtering and cooling system and a process thereof.
Background
At present, the development trend of drilling technology in China is from shallow to deep. In the aspect of shale gas exploitation, the shale gas exploitation technology capability of 3500m shallow shale gas exploitation is provided at home at present, the shale gas resource ratio of 3500-4000 m is larger, but the matched exploitation technology is not mature. Wherein the circulating temperature in the well is generally more than 130 ℃ due to the geothermal gradient, including the conventional natural gas brook-high terraced block. For example, the circulation temperatures in northern Limonitum section of Sichuan and in the middle of Xinjiang tower are both greater than 130 ℃ and up to 170 ℃. In particular to a high-temperature horizontal well, due to the fact that the high-temperature well section is long, drilling fluid is gradually heated to be close to the temperature of a stratum, the performance of the drilling fluid is influenced, and the cooling effect of the drilling fluid on a measurement while drilling instrument and a drill bit is reduced.
At present, domestic measurement while drilling systems can generally bear the high temperature of 120 ℃ of the circulating temperature. Under the downhole condition that the circulating temperature is higher than 130 ℃, the failure rate of the instrument is higher. Under the condition, how to realize the cooling of the high-temperature deep well drilling fluid is very important.
For example, patent documents with publication number CN 110284845 a, entitled drilling fluid forced cooling device and low-temperature circulation drilling method, which are published in 9, 27, 2019, describe a drilling fluid forced cooling device, which includes a secondary refrigerant cooling system and a heat exchange system, wherein the secondary refrigerant cooling system and the heat exchange system are connected in series in the device, and also describe a low-temperature circulation drilling method of the drilling fluid forced cooling device, which adopts the drilling fluid forced cooling device to control the entry temperature of the drilling fluid between 40 ℃ and 50 ℃, including the drilling fluid cooling circulation and the secondary refrigerant cooling circulation. Although the cooling device can solve the technical bottleneck that the circulation temperature of the drilling fluid caused by the ultra-high temperature in the well exceeds the temperature-resistant limit of the downhole tool, the circulation temperature of the drilling fluid can be effectively reduced by reducing the well-entering temperature of the drilling fluid, and the service life of the downhole tool is prolonged. However, the device is only provided with one set of heat exchange cooling equipment and matched pipelines, and once the heat exchange cooling equipment breaks down and needs to be overhauled, the drilling operation can only be stopped. In addition, the device has the problems of complex structure, large occupied area, inconvenience in moving and transportation, numerous valves needing to be controlled, incapability of monitoring the temperature, pressure and the like of each pipeline and medium in real time and the like.

The seventh valve 21 and the second valve 16 are in a normally closed state.
As shown in fig. 1, the process flow of the automatic drilling fluid filtering and cooling system is as follows:
opening a fourth valve 18, a sixth valve 20, a twelfth valve 26 and a sixteenth valve 30 by using a central controller, starting a first sand pump 5, and enabling high-temperature drilling fluid to flow through the fourth valve 18, the first sand pump 5, a rubber expansion joint 12, the sixth valve 20, a first flow regulating valve 13, a first pressure sensor, a first temperature sensor, a first flow sensor and the twelfth valve 26 from a hot mud pool 1 and then enter a first plate heat exchanger 9; meanwhile, the central controller is used for opening the eighth valve 22, the tenth valve 24, the thirteenth valve 27 and the seventeenth valve 31, the first water pump 7 is started, and the low-temperature cooling water flows through the eighth valve 22, the first water pump 7, the rubber expansion joint 12, the tenth valve 24, the second flow regulating valve 14, the second pressure sensor, the second temperature sensor, the second flow sensor and the thirteenth valve 27 from the cooling water pool 3 and then enters the first plate heat exchanger 9.
After heat exchange between the high-temperature drilling fluid and the low-temperature cooling water is carried out in the plate heat exchanger 9, the low-temperature drilling fluid sequentially enters the cold mud pool 2 through the sixteen-number valve 30 and the third temperature sensor, the high-temperature cooling water sequentially enters the cooling tower 4 through the seventeen-number valve 31 and the fourth temperature sensor, the high-temperature cooling water is cooled in the cooling tower 4 and then enters the cooling water pool 3 again, and the process is carried out in a circulating mode to continuously reduce the temperature of the high-temperature drilling fluid.
The flow of the high-temperature drilling fluid is controlled to be 100-160 m3The temperature of the high-temperature drilling fluid before cooling (namely the first temperature) is 40-80 ℃, and the temperature of the low-temperature drilling fluid after cooling (namely the second temperature) is 20-40 ℃. Temperature of low-temperature cooling water before heat exchange(i.e., the third temperature) is controlled to be 10 ℃ to 35 ℃, and the temperature of the high-temperature cooling water (i.e., the fourth temperature) after heat exchange is 20 ℃ to 35 ℃.
When the pipeline where the first sand pump 5 is located breaks down, the fourth valve 18 and the sixth valve 20 are closed, the third valve 17 and the fifth valve 19 are opened, and the second sand pump 6 is started.
When the pipeline where the first water pump 7 is located breaks down, the eighth valve 22 and the tenth valve 24 are closed, the ninth valve 23 and the eleventh valve 25 are opened, and the second water pump 8 is started.

When first temperature sensor and third temperature sensor show that the cooling effect is poor (for example, when the difference in temperature of drilling fluid before and after the cooling is less than 15 ℃), accessible first flow control valve 13 reduces the flow of drilling fluid this moment, also can increase the flow of cooling water through second flow control valve 14 to promote the cooling effect.
When the second temperature sensor and the fourth temperature sensor show that the temperature difference is too low (for example, the temperature difference of the cooling water before and after cooling is less than 5 ℃), the utilization rate of the cooling water is low, and the flow rate of the cooling water can be reduced through the second flow regulating valve 14 at the moment so as to improve the utilization rate of the cooling water.
When the first pressure sensor or the second pressure sensor shows abnormality, both can be controlled by the corresponding first flow regulating valve 13 or the second flow regulating valve 14. For example, if the normal pressure range of the first pressure sensor is 0.4MPa to 0.6MPa and the normal pressure range of the second pressure sensor is 0.16MPa to 0.18MPa, the indication of the first pressure sensor or the second pressure sensor is not in the normal pressure range (for example, the indication of the pressure of the first pressure sensor is greater than 0.6MPa or less than 0.4MPa, and the indication of the pressure of the second pressure sensor is greater than 0.18MPa or less than 0.16MPa), it can be regarded as abnormal.
