According to the technical scheme, if the fact that the underground inefficiency event occurs in the well drilling is determined, the actual torque friction coefficient and the simulated torque friction coefficient of the current drill string are determined; determining that the downhole inefficiency event is a downhole stick-slip inefficiency event according to the actual torque friction coefficient and the simulated torque friction coefficient; the simulated torque friction coefficient is determined according to the drilling data of the well completion target reference well; the target reference well is the same block as the well being drilled. By executing the scheme, the underground stick-slip inefficiency event can be timely and accurately determined, so that the severity of the inefficiency event can be timely analyzed, and the site drilling construction efficiency can be improved.
Fig. 2a is a flowchart of a method for determining a downhole stick-slip inefficiency event according to an embodiment of the present invention, where the embodiment is optimized based on the above embodiment. As shown in fig. 2a, the method for determining a downhole stick-slip inefficiency event according to an embodiment of the present invention may include:
if it is determined that a downhole inefficiency event is occurring in the drilling process, the actual torque coefficient of friction and the simulated torque coefficient of friction of the current drill string are determined S210.
The details of this step are described in the above embodiments.
And S220, determining a preset stick-slip coefficient threshold value of the current drill string.
The preset stick-slip coefficient threshold may be a critical value for determining an underground stick-slip inefficiency event, and may be set according to actual needs, for example, the preset stick-slip coefficient threshold may be 1.2, the preset stick-slip coefficient threshold may also be 1.5, and the preset stick-slip coefficient threshold is greater than 1.
And S230, determining that the downhole inefficiency event is a downhole stick-slip inefficiency event according to the actual torque friction coefficient, the simulated torque friction coefficient and the preset stick-slip coefficient threshold.
According to the scheme, whether the downhole inefficiency event is the downhole stick-slip inefficiency event can be determined according to the actual torque friction coefficient, the simulated torque friction coefficient and the preset stick-slip coefficient threshold.
In this embodiment, optionally, determining that the downhole inefficiency event is a downhole stick-slip inefficiency event according to the actual torque friction coefficient, the simulated torque friction coefficient, and the preset stick-slip coefficient threshold includes: determining an actual stick-slip coefficient of the current drill string according to the ratio of the actual torque friction coefficient to the simulated torque friction coefficient; and if the actual stick-slip coefficient is determined to be larger than the preset stick-slip coefficient threshold value, determining that the downhole inefficiency event is a downhole stick-slip inefficiency event.
The scheme can determine the actual stick-slip coefficient of the current drill string by the ratio of the actual torque friction coefficient to the simulated torque friction coefficient; and if the actual stick-slip coefficient is determined to be larger than the preset stick-slip coefficient threshold value, the actual torque friction coefficient is larger than the simulated torque friction coefficient in the ideal state without the underground inefficiency event, and the underground inefficiency event is determined to be the underground stick-slip inefficiency event. If it is determined that the actual stick-slip coefficient is less than or equal to the preset stick-slip coefficient threshold, other types of downhole inefficiency events are determined to occur. The method can be used for efficiently and accurately determining the downhole stick-slip inefficiency event.
In this embodiment, optionally, before determining that a downhole inefficiency event is occurring if drilling is underway, the method further comprises: determining in real time the actual mechanical specific energy and the simulated mechanical specific energy associated with the drilling process; the simulated mechanical specific energy is determined from drilling data of the target reference well; determining that a downhole inefficiency event is occurring while drilling, comprising: determining from the actual mechanical specific energy and the simulated mechanical specific energy that a downhole inefficiency event occurred with the drilling.
Because the downhole stick-slip inefficiency event belongs to the downhole inefficiency event, the present solution first requires determining the downhole inefficiency event by the actual mechanical specific energy and the simulated mechanical specific energy associated with the drilling well before determining the downhole stick-slip inefficiency event. The mechanical specific energy is the energy used to drill a unit volume of rock and is calculated as follows:
where TOR represents torque, RPM represents rotary table rotational speed, ROP represents rate of penetration, WOB represents weight on bit, and Dia represents wellbore diameter.
The actual mechanical specific energy is therefore determined based on the torque being drilled, the rotary table rotational speed, the rate of penetration, the weight-on-bit, and the wellbore diameter, and based on the torque of the target reference well, the rotary table rotational speed, the rate of penetration, the weight-on-bit, and the wellbore diameter. By determining the downhole inefficiency event, a reliable data basis may be implemented for subsequent determination of the downhole stick-slip inefficiency event.
In this embodiment, optionally, determining that the downhole inefficiency event is occurring in the well based on the actual mechanical specific energy and the simulated mechanical specific energy comprises: determining a mechanical specific energy coefficient from a ratio of the actual mechanical specific energy to the simulated mechanical specific energy; determining that a downhole inefficiency event occurs in the positive well according to the mechanical specific energy coefficient and the preset stick-slip coefficient threshold.
The scheme can determine the mechanical specific energy coefficient according to the ratio of the actual mechanical specific energy to the simulated mechanical specific energy, and then determine whether a downhole inefficiency event occurs in the drilling process according to the mechanical specific energy coefficient and a preset stick-slip coefficient threshold value. It can be realized to provide a reliable data basis for subsequent determination of downhole stick-slip inefficiency events.
In this embodiment, optionally, determining that the downhole inefficiency event occurs in the drilling based on the mechanical specific energy coefficient and the preset stick-slip coefficient threshold includes: and if the mechanical specific energy coefficient is larger than the preset stick-slip coefficient threshold value, determining that the downhole inefficiency event occurs in the drilling process.
If the mechanical specific energy coefficient is determined to be larger than the preset stick-slip coefficient threshold value, the actual mechanical specific energy is larger than the simulated mechanical specific energy in an ideal state without the underground inefficiency event, and the underground inefficiency event is determined to happen when the well is being drilled. The method comprises the step of determining that no downhole inefficiency event occurs in drilling if the mechanical specific energy coefficient is smaller than or equal to a preset stick-slip coefficient threshold value. By determining the downhole inefficiency event, a reliable data basis may be implemented for subsequent determination of the downhole stick-slip inefficiency event.
Exemplary, as shown in fig. 2b, monitoring and analyzing the well A in the interval of 6:00 day of 5 months 18 to 20:30 day of 5 months 18, and calculating the actual stick-slip coefficient and the mechanical specific energy coefficient of the current drill string of the well A by real-time monitoring of the mechanical specific energy data and combining engineering curve data, and comparing the actual stick-slip coefficient and the mechanical specific energy coefficient with a preset stick-slip coefficient threshold value to obtain the condition of the downhole stick-slip inefficiency event of the well A. Through comparison, the occurrence of underground low-efficiency events in time periods of 9:30-10:30, 10:30-11:24, 15:50-16:20, 17:24-18:00 and the like is found, according to comparison analysis of actual stick-slip coefficients and preset stick-slip coefficient threshold values, the occurrence of underground stick-slip low-efficiency events in the time periods of 10:30-11:24, 17:24-18:00 is found, other types of low-efficiency events in other time periods are found, the more accurate judgment of underground specific low-efficiency event types is realized, and by accurately judging the low-efficiency event types, targeted measures are adopted, so that safe and efficient power-assisted drilling construction is realized, and the service life of a drill bit is prolonged.
In one possible embodiment, optionally, the determining of the target reference well includes: determining target block information of the drilling well, and determining at least one drilling completion information in the target block; determining at least one formation information encountered by the drilling rig; determining the drilling data of the drilling well and the drilling data of each finished drilling well; for any formation, the drilling data of the formation is consistent with the drilling data of the formation being drilled, and a finished well in which no inefficiency event has occurred is taken as a target reference well.
The method and the device can determine the block where the well is drilled, namely target block information. Then determining the well completion in the target block, namely the well completion information. And determining well drilling data and well logging data of all wells in the target block. And (5) determining the stratum encountered by the well completion drilling for each well completion through big data screening. For each formation, if there is lithology data in the formation being drilled that is consistent or most similar to lithology data of the completed well in the formation, and the completed well has no downhole inefficiency event at that interval, such a completed well may be taken as a target reference well.
For example, assuming that there are 9 completed wells in the same block as the well being drilled, a 500-800 meter simulation is performed to divide into multiple formations, and if there is only the first section of sandstone for the first formation for the six completed wells, the six completed wells are screened out. And continuing to screen the six well completion wells, and taking the well completion wells with consistent drilling engineering parameters when drilling the sandstone sections and without the occurrence of a downhole inefficiency event in the sections as target reference wells. It may be realized to provide a reliable data basis for subsequent determination of downhole inefficiency events and downhole stick-slip inefficiency events.
According to the technical scheme, if the fact that the underground inefficiency event occurs in the well drilling is determined, the actual torque friction coefficient and the simulated torque friction coefficient of the current drill string are determined; determining a preset stick-slip coefficient threshold of the current drill string; and determining that the downhole inefficiency event is a downhole stick-slip inefficiency event according to the actual torque friction coefficient, the simulated torque friction coefficient and a preset stick-slip coefficient threshold. By executing the scheme, the underground stick-slip inefficiency event can be timely and accurately determined, so that the severity of the inefficiency event can be timely analyzed, and the site drilling construction efficiency can be improved.
